(notice) child pid XXXX exit signal Segmentation fault (11), possible coredump in /etc/apache2

Question

I keep getting the follow error in my Apache log:

[Wed Sep 18 17:59:20 2013] [notice] Apache/2.2.22 (Ubuntu) PHP/5.3.10-1ubuntu3.8 with Suhosin-Patch configured          


        

Answer 1

This problem is often caused by an Apache module. As you can see, the other answers are about a module or another. The generic answer could be try to disable the last module(s) you enabled.

In my case, the module causing the problem is php7.3, on Ubuntu 18.04. PHP 7.2 works, but not PHP 7.3.

Answer 2

After an entire day of trying to trace this down, no solutions worked. I eventually however turned Apache to debug level logging and immediately noticed hundreds of notices/warnings with Google's mod_pagespeed for Apache trying to rewrite images from Jetpack's Photon images.

I did a simple a2dismod pagespeed and no more segmentation faults.

Have also noticed my sites are actually running faster now with mod pagespeed turned off.

There seems to be quite a few bug reports about pagespeed causing segmentation faults.

Not sure if its just mod_pagespeed or the combination of mod_pagespeed, wordpress and php .... but turned off now problem gone.

I am done with it for now and also in the process of moving everything to Nginx now. Tracing faults on Apache always turns into a nightmare, with Nginx I can find errors in a few seconds to a minute.

Answer 3

I just restarted Apache and the problem gone

Answer 4

I solved this indirectly. I put Nginx in front of Apache and I no longer have segmentation errors. Having Nginx in front of Apache is a better set up in my opinion. Varnish Cache may have also solved the problem.

Answer 5

I was having this exact error and I just restarted the server (restarting apache didn't help).

Might consider it if you've just done a apt upgrade
